[control of 1B-2. charging arms]
ECU40 executes charging arm control as described below.That is, in the case where the arm 26 that charges is not deployed, ECU40 judges arm
Whether 26 expansion starts condition true.Start condition as the expansion, such as enumerates the case where expansion switch 38 is connected.
On this basis or it is replaced in this, it can also be by the vehicle 12 and contact power supply on the direction of travel of vehicle 12
112 or the distance (travel direction distance) of guide portion 124 become the following situation of defined threshold value (distance threshold) as expansion
Beginning condition.In order to judge travel direction distance, such as current location detection (not shown) can be pre-set on vehicle 12
Device (for example, navigation device) and the map data base for storing the location information for electric installation 14 (contact power supply 112).And
And can calculate travel direction distance as vehicle 12 current location with contact power supply 112 position at a distance from.
Alternatively, can in vehicle 12 and the communication device for pre-setting short-range communication on electric installation 14 respectively,
It is determined as that beginning condition, which is unfolded, to be set up when establishing communication between two communication devices.
In the case where the establishment of beginning condition is unfolded, ECU40 executes the exhibition for making the arm 26 in receiving state be unfolded
Open processing.Rotation angle θ (Fig. 2) variations of arm 26 as a result, arm 26 from the vehicle body of vehicle 12 state most outstanding is close to divide
Power supply 140.
In such a state, ECU40 judges whether the expansion termination condition of arm 26 is true.Terminate item as the expansion
Part can enumerate the case where for example expansion switch 38 disconnects.
On this basis or it is replaced in this, item can also be terminated as expansion using the case where the charging complete of accumulator 24
Part.The completion of charging can reach the case where defined threshold value (SOC threshold) by SOC or the voltage of accumulator 24 reaches rule
The case where fixed threshold value (battery tension threshold value), is judged.
Alternatively, can in vehicle 12 and the communication device for pre-setting short-range communication on electric installation 14 respectively,
After establishing communication between two communication devices, it is determined as that termination condition, which is unfolded, to be set up when breaking in the communications.
In the case where termination condition establishment is unfolded, ECU40 executes the storage for storing arm 26 and handles.
[power supply control in 1B-3. external powering devices 14]
Fig. 6 is the flow chart of the power supply control in the external powering device 14 of present embodiment.In step sl, control dress
122 are set to determine whether to execute power supply.The judgement from manager via input unit 120 for example by whether have input defined finger
It enables or whether the instruction effectively judges.
(the S1 in the case where being not carried out power supply：It is no), repeat step S1.(the S1 in the case where executing power supply：It is),
In step s 2, control device 122 makes each segmentation power supply 140 become the state that can be powered.Specifically, control device
122 to external transducer 114 each switch element (not shown) discontinuously or continuously output drive signal Sd2 and by power supply 110
It is connect with segmentation power supply 140.Respectively segmentation power supply 140 becomes the state that can be powered as a result,.Also, in arm 26 by electricity
When portion 52 is contacted with segmentation any of power supply 140, via the segmentation power supply 140 carry out from for electric installation 14 to vehicle
12 power supply.
At this point, control device 122 is so that the output voltage (supply voltage Vs) of segmentation power supply 140 is periodically increased
Mode controls the step-up ratio of converter 114.But it should be noted that the supply voltage Vs of each converter 114 becomes fixed value
Situation (with reference to Fig. 7).
Fig. 7 is the distance L for indicating the beginning place Pst away from guide portion 124, the output voltage Vs for dividing power supply 140
Desired value (target output voltage Vstar) and the input current Ibatin (hereinafter also referred to " input currents inputted to accumulator 24
Ibatin ") relationship an example figure.Beginning place Pst said here refers to the guide portion on the direction of travel of vehicle 12
The place of 124 most front side.
In other words, the example of Fig. 7 is position and guide portion of the power receiving section 52 of arm 26 from the most front side of guide portion 124
The example of the case where 124 contact.Therefore, power receiving section 52 from the midway of guide portion 124 or divide power supply 140 a part into
Row contact in the case of, should be noted that the example of Fig. 7 since midway start as waveform the case where.
As shown in Figure 5 and 7, in turn that the target for dividing power supply 140 is defeated before direction of travel from guide portion 124
Go out voltage Vstar be set to it is higher.In other words, in the segmentation power supply 140 of the range before distance L becomes L1, so that defeated
Going out voltage Vs, periodically respective target output voltage Vstar is set as fixed value by increased mode.For example, from front side
When observation, the target output voltage Vstar of first segmentation power supply 140 is Vstar1, the mesh of second segmentation power supply 140
It is Vstar2 to mark output voltage Vstar.Inhibit the phenomenon that dash current enters vehicle side converter 28 as a result, can inhibit to turn
The switch element (not shown) of parallel operation 28 or the damage of accumulator 24.
In the segmentation power supply 140 of the range after distance L becomes L1, in a manner of so that output voltage Vs is become constant
Target output voltage Vstar is set as fixed value.
Control device 122 carries out the processing of Fig. 6 according to each specified period (for example, with 0.1~3 second interval).
In addition, in the figure 7, after distance L becomes L2, although keeping target output voltage Vstar, input current
Ibatin also declines.This is the charging progress along with accumulator 24 and the subtractive of the voltage and output voltage Vs of accumulator 24 is small
Result.When distance L becomes L3, arm 26 is detached from contact power supply 112, terminates charging.In the example of fig. 7, from L2 when
It is that input current Ibatin continuously declines as a result, in L3 become zero.That is, indicating that accumulator 24 becomes the feelings full of electricity condition
Condition.
[power control in 1B-4. vehicles 12]
Fig. 8 is the flow chart of the power control in the vehicle 12 of present embodiment.In step s 11, ECU40 judges arm 26
Whether it is in expansion.Expansion of the judgement for example based on charging arm control starts whether condition carries out at Rob Roy.
(the S11 in the case where arm 26 is not in expansion：It is no), repeat step S11.In the case where arm 26 is in expansion
(S11：It is), in step s 12, ECU40 stops the transformation being carried out by converter 28, executes the electric power of self-power supply device in future 14
The direct connection processing directly fed to accumulator 24 etc..In this case, continuously (that is, with duty ratio 100%) is defeated by ECU40
Go out the drive signal Sd1 (Fig. 1) for converter 28.Accumulator 24 and power receiving section 52 are from non-electric-connecting state to electricity as a result,
Connection status shifts.
In step s 13, ECU40 judges whether the expansion of arm 26 terminates.The judgement is for example based in charging arm control
Whether expansion termination condition carries out at Rob Roy.
In the unclosed (S13 of expansion of arm 26：It is no), return to step S12 continues direct connection processing.In arm
(S13 in the case that 26 expansion terminates：It is), in step S14, ECU40 makes direct connection processing terminate.Accumulator as a result,
24 become non-electric-connecting state with power receiving section 52.After step s 14, the return to step S11 after it have passed through the stipulated time.
The effect of 1C. present embodiments
As described above, according to the present embodiment, to (the segmentation of multiple segmentation power supplies 140 being arranged along traveling road 132
Power line) apply defined voltage by towards direction of travel it is raised in a manner of set (Fig. 5 and Fig. 7).It is filled therefore, it is possible to reduce
The voltage difference of power supply 112 (power line) and power receiving section 52 when establishing the beginning by cable or in charging.Therefore, it is possible to realize vehicle 12 by
